is there a book which treats To Kill A Mocking Bird through a psychoanalitial approach?

When I googled to kill a mockingbird psychological analysis, all I got were the Sparknotes, Bookrags, novelguide, etc., websites -- or psychological analyses of other books and their characters.

You may have to google each character, as linked at the very bottom of the search results page:
